FLAGSTAFF.

Specification of Letters Patent.

Patented Mar. 39, 1915.

Application filed July 7, 1914. Serial No. 849,607.

To all whom 'it may concern Be it known that T, MARTIN T. OLsTAD, acitizen of the United States, residing at Greeiiport, in the county ofSuffolk and State of New York, have invented new and useful improvementsin Flagstaifs, of which the following is a specication.

The general object of this invention is to invite a flag or pennantcarried on a flagstaff and secured to a mast head to fly clear and openfrom the staff, and also to prevent the possibility of the flag orpennant from wrapping around the staff from such causes as bv the windsuddenly changing direction. And to these ends the invention consists ofa flagstafl1 having a butt provided with a rod at one end thereof, and arotatable and ball bearing flag holding section connected to the rod.

Other objects will appear and be better understood from that embodimentof my invention of which the following is a specification, referencebeing had to the accompanying drawings, forming part hereor, in whichFigure 1 is an elevational view of a portion of a mast showing myimprovedpole mounted in positionI thereon. Fig. 2 is an enlarged detailvertical sectional view of a portion of the pole. Fig. 3 is a sectionalplan on the line 3-3 in Fig. 2. Fig. 4L is a detail dissectedperspective of the cojoining` ends of the pole-section.

As shown in the drawings the flagstaif a is preferably formed in twosections and c which are retained in pivotal relation with each other bythe axle member CZ.

The butt portion of the section b which is indicated by 5 is preferablyformed of wood or the like and is solid in structure. The upper end ofthe butt is reduced in diameter as shown at 6, whereby to have mountedflush with the periphery of the same the cylinder or tubular casing 7,and by referring to Fig. il, it will be seen that the upper end 6 of thebutt is recessed so as to provide a diametrically arranged slot 8. Thisslot is preferably of suiiicient depth to have litted therein the blade9 of the member d, which may be secured in place by the bolt 10 or thelike; and carried by the blade 9 is a cylindrical rod or upright 11, bymeans of which the section c is secured to the section as will behereinafter described.

As shown in Fig. 2 the tubular casing 7 extends beyond the upper end ofthe portion 6, and arranged snugly within the casing so as to rest onthe upper end of the portion 6 is a collar or gasket 12, which iscentrally bored so as to have fitted therein the slightly reduced end ofa tube or sleeve 13; which surrounds the rod 11, and is secured thereonby a nut lt provided on the upper end of the rod as shown. A suitablespacing sleeve 15 is fitted within the cylinder 7 so as to carry the endpiece 16, and for the purpose of retaining the sleeve 15 in place,suitable bolts 17 are employed as shown.

The section c includes a portion 18 which 1s similar in structure to theportion 5 before mentioned, and is provided with a reduced portion 19over which is mounted the tubular casing 20 which is secured to theportion 18 by such means as the bolts 21. The casing 20 is similar tothe casing 7 and extends beyond the end of the portion 21, as shown.Arranged at the end of the casing is a centrally bored end piece 22which is fitted snugly therewithin, and secured within the casing by thebolts 23 is a spacing sleeve 24; which bears against the end piece 22.This spacing sleeve is provided for the purpose of carrying the cup 25,which is fitted relatively snugly within the casing and is centrallybored so as to permit the projection therethrough of the tube 13 andupright 11; and bearing on the cup 25 is a second cup 26 which isinverted as shown. These cups are arranged so as to be in peripheralspaced relation with an annular shoulder 27 between which and the cupsare arranged a plurality of ball bearings 2S which thus admit of thesection c being rotated on the member Z carried by the section b.Bearing on the inverted or upper cup 26 is a spacing sleeve 29, which ispositioned within the cylindei, and which spaces the cups 25 and 26. Asecond pair of cups 30 and 31 surround a second shoulder 32 carried bythe tube 13, and have fitted between them a plurality of balls For thepurpose of retaining the upper cup 31 in operative relation with the cup30, a sleeve 33 is fitted within the cylinder so as to bear against thecup 31, and is secured in place by the bolts 34E.

It is quite obvious that the parts are generally assembled within thesection c before the same are mounted on the top portion 19, and for thepurpose of reducing the thrust friction to a minimum when the sectionsare rotated, a suitable disk 36 is provided on the tube 13, so as to belocated between the adjacent ends of the two sections. This disk isprovided within va series of perforations or openings Vwherein arepocketed suitable.

lball-bearings 37, which rotate against the top end of the section whenthe sections are in motion.

It is obvious that those skilled in the artA may vary the details ofconstruction and arrangements of parts Without departing from the spiritof rnyinvention and therefore I do not wish to` be limited to suchfeatures eX-` cept as may be required by the claims.

What I claim as new is 1. A iiagstaf comprising a butt, a rod rigidlyconnected at one end to the butt andY provided with a plurality ofspaced shoulders,a top section, a cylindrical casing connected to thelower end of the top'section and fitted over the rod, a plurality ofbear- Y ing cupsarranged in spaced relation on the casing and opposed tothe shoulders, balls tted between the cups and the shoulders, spacingcollars fitted within the `casing' for retaining the cups in relativeposition to the shoulders and a ball bearing disk arranged between theadjacent ends ofV the butt'and"V ltop sections yfor the purposes setforth. j

2. A flagstatf comprising a butt, havinga diametricallv arranged slot atthe upper end thereof,a rod having a blade adapted to beV itted withinthe said slot,'so as to' position the rod on the butt in a non-rotatablemanner, said rod provided with a plurality of annular shoulders arrangedin spaced relation, a top section, a cylindrical casing connected to thetop section so asY to surround the rod, a plurality of bearing cupsarranged in spaced relation withinthe casing and opposed to theshoulders, ballsittedV Y within the cups and between the `cups andMARTIN T. oLsTAD. 1
